Working Principle

The V28A28H200BF3 DC-DC converter works by using an internal DC-DC buck converter to convert the input voltage to an output voltage and current. The converter uses a voltage controlled switch (transistors) and an inductor to regulate the output voltage and current. The transistors are used to switch the inductor on and off at a fixed frequency, while the inductor limits the amount of current that can flow through the circuit. The output voltage is regulated by using a feedback circuit to ensure the output voltage is kept within the specified tolerance.
